To all whom 'it may concern.'

Be' it known that we, CHRISTIAN MADsnN and ADoLrH A. KoLLMoRGEN, citizens .of the United States, residing at Penn, in the county of Ramsey and State `of North Dakota, have invented certain new and useful Improvements in Dairy-Cans, of which the following is a specification.

Our invention relates to cans which are used for the transportation and carrying of milk, cream and other dairy products, and the object of the invention is to provide a can which is safe, sanitary and which may be easily cleaned.

A further object is to provide a can of a simple construction, but yet which shall be so strong asto withstand the rough usage which is incidental to ordinary service.

Further objects are to improve the de tailed construction of this form of can in a manner which will be pointed out in the fol lowing specification.

Our invention is shown, in the accompanying drawings, wherein: v

Figure 1 is a perspective view of our improved can; Fig. 2 isa plan view thereof; Fig. 3 is a4 vertical diametrical section; and, Fig. 4 is a fragmentary enlarged vertical section onthe line 4-4 of Fig. 2.

Corresponding and like parts are referred to in the following descri tion and indicated in all the views of t edrawings by the same reference characters.

Referring to these figures, 2` designates a can having upwardly and inwardly inclined sides, the lower edge of the sides being inwardly curved, as at 4, and merging 'into a R' flat bottom 3.

The upper end of the can is formed4 with a beadv 5 inclosing a ring 6 which strengthens the upper end of the can and also forms an outwardly projecting flange surrounding the top of the can. Immediately beneath the bead 5 is the reinforcing ring 7 which lits against the side of the can and is held in its place by the outward inclination of the sides. This ring 7 is provided with'ears 11,

as will be later described, and suitable handles.

Attached in any suitable mannerto the bottom of the can is the reinforcing plate 8 which has the downwardly turned marginal flange 9. This circumferential' llange 9 is riveted or otherwise attached to base ring or annular member-10, which surrounds the Y lower curved portion of the can and" projects slightly above the same so as to cover the space left by the inward curvature of the base of the can and prevent the collection of dirt therein. Likewise this annular band l() acts to reinforce the base of the can and to reinforce the downwardly extending flanges 9. The band 10 is riveted or otherwise attached to the can body, but preferably in such manner that no projections shall ex@ tend inward from the inside face of the can so that the inside face of the can may be perfectly smooth and continuous. The upper end of the can *body is provided with the oppositely disposed pairs ot' projecting ears 1l, these ears being provided with perorations or slots l1EL for engagement-with the cover as will bc now described. Preferably, these ears l1 are attached to the band orring 7 so that strain Acoming upon these ears will not tend to deform the 'can body itself, but will be borne by the relatively thick and rigid reinforcin band or ring 7.

The cover of the can is ormed of a circular plate of metal and designated 13. This plate is cireumferentially flanged, as at 14,

so as to fit over the 'bead 5 and inward of this flange is disposed the annular ring 15 having the form in cross section shown in Fig. 4. This ring is widened at its lower edge, or in other words, is undercut, and located between the ring and the flange 14 is thel filling 16 ofV cork or other like suitable material which is vheld in placeby lthe undercut-ting of the flange 15. When the cover is in place upon the can, this filling will rest upon the bead 5 and thus make an air tight joint between the cover and the body of the can.

As a means of holding the cover in place, we preferably provide the oppositely disposed loeking bars 17 which are mounted to slide in guides or .straps 18 riveted to the the ears 11 on one side of the can, while diaxuetrically opposite to the locking bars I7 are the projecting lugs 19 which are riveted to the cover and which extend outwardly therefrom and are slightly curved so as to engage with the perforations in the ears 11. For thc purpose of shifting the locking bars 17 we provide upwardly projecting hearings 20 on the cover through which pass the ends. of the bowed handle 21 .so that the handle muy have rotative movement iu the bearings. The extremities of the projet-.ting ends of the handle are inwardly bent, as at 22, and engage in recesses 93, formed one in the end of each of the locking bars. rFhus upon a rotative movement of the handle, the locking bars will be Ishifted either into operative or inoperative position.

.lt is, of course, preferable to provide some means whereby the l1andle21 shall beheld in its two horizontal positions, and for this' purpose we provide the spring 24 which is attached at 25 to the cover, the ends of the spring extending outward from the face of the cover. lhe ends of thc spring extend up beneath the bent ends ofthe handle 21 and thus tend to hold the handle 2l in either one of its l'lorizon'tal positions, the spring resisting the turning of the handle, but, of course, yielding when the handle is forcibly moved over. Also formed upon the cover is the upwardly projecting lug 2G having a perforation which when the handle is in its locking position, is in approximate alinement with a perforation on the handle. Through these two perforationsa sealing strip 28 may bepassed. Attached to the ring .or band 7 are the oppositely disposed drop-handles 29 of any suitable character. The locking ends of a bar 17 which with the ears 11 hold the lid or cover in place, are preferably thin at their. outer ends, but made slightly wedge-shaped so that when they are forced into the elves in the ears 1l, they will act to force t e lid downward into tight contact with the can.

Having thus described the inventiomwh at is claimed as new is:

1 A milk can having an upwardly and inwardly inclined side wall, the upper end of said side wall being outwardly beaded, a reinforcing wire extending through said bead, and a reinforcin annular bandysurrounding the upper en of the can just below said bead and holding the bead closed on the wire.

2. A milk can having an upwardly and inwardly inclined wall, the upper endof the wall being outwardly beaded, a ring extend.

ing through said bead, an annular reinforceing band extending around the, upper end of the can immediately beneath the bead and holding said bead closed on the ring, handles on the band, a cover, and attaching devices on the cover engaging said band to hold the cover in place.

3. A milk can having an upwardly and inwardly inclined side wall and a flat bottom, the junction between the wall and bottom being curved, the u per end of said can being outwardly bea ed, a reinforcing ring located below the beaded edge of the can und having upwardly extending perforated lugs thereon, a cover closing the mouth of the can, slidable locking bars' mounted on the cover and engafring said lugs to hold the cover in place, andD a handle engaging said locking bars to shift the same into their locked or unlocked position.

4. A milk can having an outwardly beaded upper edge and a cover therefor having a downwardly turned circumferential flange, a flange on the cover extending downward interiorly of the circumferential flan e below the plane of the inner face o said cover, said last named flange being undercut on its outer face, a filling of yielding material supported between the two flanges, and lne-ans .for detachably engaging the cover with the can.

5. The combination with a milk can hav ing oppositely disposed pairs" of upwardly projecting lugs on its upper end, of a cover therefor having a air of lu s projecting beyond the circum erence an adapted to engage with one of said pairs of lugs on the ca n, shiftable parallel locking bars engaging with the other pair of lugs, guides in which said bars move, and a rotatable handle the ends thereof engaging with said locking bars to shift the same when the handle is turned, and means for yieldin'gly holding the handle in position against the cover.

6. The combination with a milk can, of a cover therefor having a downwardly turned circumferential flange 'and an interior flange on the under side o the cover concentric to' the circumferential flange, said interior flange being formed of a foldedl strip that portion forming the outside face of the flange being inwardly bent to the inner faceof the cover to forman undercut'outer face for the inner flange, a fillin of yielding material supported between t e outer and inner flanges and engaging beneath the undercut portion of the inner lflange, and means for detachably engaging the cover with the can.

7 The combination with a milk can having oppositely disposed pairs of u Wardly projecting lugs on its upper end, o 'a coyer therefor 'having a pair of lugs pro ectln beyond the l circumference thereo adapted to engage with one of said airs of lugs. on the can, shiftable parallel ockin'g hars engaging with the -other pair of lugs, guides 1n which said bars move, upwardly projecting ears on the cover, a rotatably bowed handle mounted in said earsiand hav- 51m eye l'ocated adjacent to the handle when i in its loekingpos'tion and .adapted to4 rec eive a sealing wire.
